“…During the time of deposition of the Lower Cretaceous McMurray Formation, Lower Manville Group, east-central Alberta, Canada, the Western Cordillera of North America was undergoing a period of complex tectonic activity involving arc magmatism, fold-andthrust belt development, and foreland basin accumulation [26,27]. The episodic nature of these tectonic themes resulted in multiple episodes of deposition and erosion within the foreland basin beginning with the accumulation of the McMurray Formation [28].…”

Stable isotope, trace element, and cathodoluminescence analyses were performed on gastropods and matrix from rock cores of the Middle to Upper McMurray Formation (Lower Cretaceous/Aptian, Northwestern Alberta, Canada) to characterize the extent to which pristine material remained from which depositional environmental conditions could be estimated. Aragonitic gastropod shells retain their original depositional chemistry, and along with other closely associated authigenic carbonate components, indicate that the Middle to Upper McMurray Formation was deposited in a freshwater environment that was part of a continent-scale river system.
